IMPROVENIENT INIVDEVICE FOR QPERATII'IN G- GATES.

To all whpm ft ma/y concern:

Be it known that I, DAVID G. GOODALL, of Beloit, Rock county, in the State of Wisconsin, have invented certain new and useful Improvements in the Method 'of GlosingllEIand-Gates,l and Opening, Closing, and Fastening Carriage-Gates; and I do hereby declare the fol-- lowing description and accompanying drawings are sufcient to enable any person skilled in the art or science to which it most nearly`appertains,.to make and use my said invention or improvements, without further invention or experiment.

The nature of my inventionv and improvements conating carriage and hand-gates; the former by the employment of the pull-wire, which is done without alighttlrmly secured when closed, without the use of a latch. lhet'llatter is self-closing, and is held by any suitable atc Figure 1 is a perspective view of a carriage-gate, with my device for opening and closing attached thereto;

Figure 2 is a view of said opening and closing-device detached; Figure 3 is a perspective view of a hand-gate opening inward, with my device attached, in which the gate is so closed-by the pushing-action of the device in question; and

Figure 4 is a similar view of a hand-gate, opening said device. I

Bfg. 1, represents a carriage-gate.

A a are oscillating levers, attached by a loose joint to the sill P, which is fastened at right angles to the heel-post R of the gate.

A is a connecting brace-rod, the outer-end being loosely jointed tothe rail of the gate B, and to the inner ends of the oscillating levers A a, as shown, connectiugin 4the centre with each other by a' loose joint, at which place, also, the weight E is suspended.

F is a jointed check-wire or chain, the'lower end of which is made fast at the reciprocating centre joints of the brace-rod and oscillating levers in question; the upper end of which is made fast to the heel-post R of the gate, soas to prevent a too great depression-of the weight E. i

O is a double crank-lever, pivoted to the top part of the heel-post of the gate.

I is a supporting-wire to the same.

L is a draught-wire, having the upper end secured to the outward end of the' horizontal 'arm of the double crank-lever C, and the lower end attached to the inner ends of the oscillating levers A a, at or near the point at which the weight E is suspended.

D D are crank-levers, having supporting-wires I I, forming quadrants or triangles, and are pivoted to the cross-bars, at the tops ofthe pull-posts S, as shown.

The inner pull-wiresG G are attached to the inner ends or angles of the crank-levers D D, having pulls, H H, attached to the outer ends or angles thereof, the inner ends of the said pull-wires G G being fastened to the upper and lower ends, respectively, of the vertical bar of the said double crank-lever O.

The gate is opened by a rather quick draught of the pull H, at either approach to the gate, raising the weight E rather bris'kly, with the conjoining ends of the oscillating levers A a and connecting brace-rod A, to an angle of about forty-five degrees, pulling the gate open at the point of' the dead-centre of the draught, between the opening and closing, by means of said pull; but the exhaustion of the pull, I place a few inches one'side4 of the centre of gravity of .the weight, as so supported, so that the gravitation of said weight, andthe momentum acquired, shall complete the opening of the gate, when it is firmly held by said weight andV pull and reversedthe levers, until closed by the same action of said levers and weight.

This device may be attached, and employed to operate any ordinary swing or sliding gate. Fig. 3 exhibits my device applied for closing a hand` gate, pushing it to, as shown, in which E is the weight,

Az the oscillating levers, and F the check-wire, ex-- same as shown in fig. 1, excepting that the gate slides" in a perpendicular line, to act in its best position, from a point midway between the attachment of the outer ends of the oscillating levers A a, on the sill P, and the apex of said levers, the connecting-rod A acting in a straight line. What I claim as my by Letters Patent, is-

1. Broadly, the oscillating levers A a, weight E, connecting brace-rod A, and check-wire F, when constructed and arranged'as shown at g. 1,. substantially as set forth and described, when employed for the purpose of operating at gate or gates. I

2. In combination with the foregoing, the arrangement and employment of the draught-wire L, double crank-lever C, crank-levers D D, supports I I, pulls H H, pull-wires G G, pull-posts S S, post It, and sill P. 3. Broadly, the suspension of a weight on an oscil-- latingor vibrating lever or levers, to eectually close hand-gates, by either pushingor pulling them to, after being opened.
